Last of the month
The last of the month or last day of the month is the recurring calendar date position corresponding to the final day of any given month. In the Gregorian calendar (and other calendars that number days sequentially within a month), the last day varies depending on the month and, in the case of February, whether the year is a leap year.

- January 31

- February 29 (leap years)
- March 31
- April 30
- May 31
- June 30
- July 31
- August 31
- September 30
- October 31
- November 30
- December 31
